New model from HiTechnic

HiTechnic have released the building instructions for a new model, this time a small go-kart. This go cart is controlled by a Power Functions remote, that sends commands to the HiTechnic IR-Receiver sensor which in turn communicates with the NXT.

It looks quick and I'm sure would be a blast to play with. Also a nice bonus that it can be built with both the 1.0 and 2.0 NXT sets :)

I Love how they get around not needing a differential (you'll have to watch the video to find out!)

"These wheels make it go faster."Do they mean the 1.0 or 2.0 wheels. I would think the 1.0 wheels because of their larger radius, but I suppose the 2.0 wheels might have a smaller mass, which would result in higher acceleration. Either way, I imagine the result isn't exactly noticeable unless they're side by side.

Hitechnic has made some excellent models with building instructions and programs.One minor correction to your blog entry: the Hitechnic IR Kart uses the NXT IR Receiver sensor, and not the IR Link sensor.

There is a significant redundancy in the LEGO PF signal. The LEGO PF remote sends every PF IR command five times at intervals depending on the PF channel so that multiple PF remotes can be used at the same time with reasonable expectation that at least one complete command can be received for each channel from each remote. Range of the IR RC Kart is obviously line of sight and probably around 4 or 5 meters depending on lighting, IR interference etc. Using the LEGO #8885 remote it is actually quite responsive.
